Filed: 1992-03-31
Abstract: PURPOSE:To provide a signal insulating device which can reduce its power consumption and receives no influence of the external noises by using a differential pulse circuit which outputs a pulse in response to the differential pulse produced by differentiating a pulse width signal. CONSTITUTION:A pulse width output means 1 outputs the signal to be insulated by a pulse width signal. A differential pulse output means 2 receives the pulse width signal from the means 1 and outputs the partial pulses at both rise and fall edges of the pulse width signal. A 1st photocoupler(PC1) 3 is driven the differential pulse outputted at the rise edge of the pulse width signal, and a 2nd photocoupler(PC2) 4 is driven by the differential pulse outputted at the fall edge of the pulse width signal respectively. A differential pulse receiver means 5 contains the receiver resistances to receive the pulses outputted from both photocouplers 3 and 4. Then a flip-flop circuit 6 is set and reset by the pulse signal received from the means 5.

Outputs C1-Cm from a memory M take a level of '1' or '0', and when an output C1 is logical '0', an analog switch S1 is opened. The resistance of the R1-Rm is selected equal to be (r) in valve and the resistance (r) is selected sufficiently smaller than the resistance RA or RB in value. Thus, the reference voltage Vref is adjusted with high accuracy by turning on or off the switch S1 in response to the output C1 of the memory M.

Filed: 1995-04-04
Abstract: PURPOSE: To ease the burden of stirring blades, homogenize an improved columnar body, and keep the diameter of the improved columnar body constant by allowing a solidifying material or water to jet at high pressure from a nozzle provided at the end part on the outside in the radial direction of the lowermost stirring blade in order to strike the stirring shaft at the lower part below the lowermost stirring blade, and thus to cut the ground by high pressure jet, preceding the stirring blades. CONSTITUTION: A stirring shaft 11 is rotated to be gradually lowered to cut the ground 1 up to a specified improving depth. In this case, a solidifying material is jetted from a nozzle 13, and a high-pressure jet 14 takes charge of substantial cutting of the ground 1 following the guidance of a drill 15, preceding a stirring blade 12'. Further, the high-pressure jet 14 strikes the drill 15 to be diffusely reflected to limit the improved diameter of the ground 1 to the range R, which a stirring blade 12 reaches. Besides, the solidifying material is stirred and homogenized by rotating the following, respective stirring blades 12. When the stirring shaft 11 is pulled up from a cut hole, an improved columnar body is created in the ground 1. Thus this method eliminates the need for high torque for cutting the ground.
